appendix.
B.1
Direct mount
Sensor installation using mounting frames, spacer bar and spacing guides
The combination of mounting frames, spacer bar and spacing guides is the recommended
way to mount Direct mode sensors. The mounting frame establishes the axial alignment of
the sensors and allows you to remove and replace either sensor while preserving their exact
mounting location.
For Direct mode mounting, a spacer bar is used to establish the distance between sensors
and a spacing guide to locate the sensors at the nine o’clock and three o’clock positions.
Should the distance between sensors be beyond the span of a spacer bar, a measuring tape
can be used. The Mylar spacing guide comes in various lengths and widths to accommodate
most pipe sizes.

1.
Use the Wizard setup procedure to program the transmitter for the sensors that were
selected.
2. After receiving the spacing number index from the transmitter, make a note of the number
displayed then prepare the pipe surface area where the sensors will be mounted.
3. Degrease the surface and remove any grit, corrosion, rust, loose paint, etc.
